The antibacterial component, as described above, is 30 to 60 wt% of silicon dioxide (SiO ₂ ), 30 to 50 wt% of aluminum oxide (Al ₂ O ₃ ), 1 to 10 wt% of silver (Ag), 2 to 15 wt% of zinc (Zn) and 2 to 15 wt% of sodium (Na) may be included. In addition, a porous zeolite that is 50 to 500 wt% of the total antibacterial component may be prepared, and the zeolite may be made to have, for example, mesopores of 1 to 100 nm. When the antibacterial component and the zeolite are prepared, they may be mixed together to have a particle size distribution of 0.05 to 20 μm while having an average particle size of 0.1 to 10 μm. In addition, each antibacterial component may be pulverized to have an apparent density of 0.25 to 0.45 g/cm 3 to be made in a powder form (S21). The antibacterial component can be absorbed into the zeolite to generate Ag or Zn cations so that the antibacterial effect appears. When the antibacterial component and the zeolite in powder form are prepared (S21), the antibacterial component and the zeolite can be made into a master batch, for example, LDPE (Low Density Polyethylene), HDPE (High Density Polyethylene), PP (Poly Propylene). ), PS (Poly Styrene), Wax (Wax), ABS (Acrylonitrile Butadiene Styrene), PVC (Poly Vinyl Chloride) or similar polymers as a base can be made into a master batch at a concentration of 5 to 20 wt% . An antibacterial layer can be made by the master batch made in this way (S22). As described above, the antimicrobial layer can be made integral with the base layer, or can be made in the form of a film layer or a fibrous layer. For example, the film layer or the fiber layer may be made of the same or similar material as the base layer, and a master batch in the form of powder, beads, chips or pellets may be added in the process of making the film layer or the fiber layer. In this way, the antibacterial layer is prepared (S22), and when the protective layer described above is prepared with this (S23), the antibacterial layer and the protective layer may be coupled to the base layer (S24). As described above, the antimicrobial component comprising the zeolite carrier can be, but is not limited to, 0.1 to 20 wt% of the total weight of the base layer. If the antimicrobial layer is integrally formed with the base layer, the protective layer may be bonded to the base layer, and the protective layer may have a thin film structure or a coating layer. As such, when the antibacterial layer or the protective layer is combined with the base layer, the handle cover may be completed (S25).

Referring to FIG. 3 , it can be seen that the antibacterial handle cover does not discharge metal components such as Cd, Pb, Hg or Cr, and at the same time, does not discharge phenyl-related components. In addition, an oral toxicity test was conducted on mice, and the antibacterial component was administered to 10 mice at a dose level of 2000 mg/kg body weight, which is the maximum physical dose. As a result of administration, there was no death in one animal, and no weight loss was observed after administration. LD50, which is a lethal concentration of 50% of the number of experiments, was found to be high in non-toxicity over 2000mg (acute oral toxicity test). After removing the hair from the rabbit's back, 0.5 g was applied to the exfoliated skin of the keratinized skin with a well-shaped scar to the extent that it did not injure the dermis with an injection needle on the healthy skin for 24 hours, and the elapsed time was observed for up to 72 hours. However, no skin reaction by erythema occurred (skin irritation test). In the 5-level reversion mutation test in E. coli and Salmonella, regardless of the direct method, metabolic activation method, and treatment concentration, the number of revertant colonies similar to the negative control group was shown, indicating no mutagenicity (reversion mutation test). In addition, it exhibits antibacterial action against gram-negative bacteria such as Escherichia coli, Pseudomonas aeruginosa, and Salmonella, gram-positive bacteria such as Staphylococcus aureus and MRSA, fungi such as Nurufungi and blue mold, and a wide range of microorganisms such as O-157 virus. For the antibacterial component of %w/w, the D-value (reduced by 90% of bacteria) was found to be 9 minutes. As described above, it can be seen that the handle cover according to the present invention can protect the driver due to the antibacterial action without negatively affecting the driver during the use process.
